DETONATOR.

SPECIFICATION forming part of Letters Patent No. 755,934, dated March29, 1904. Application filed February 17, 1904. Serial No. 194,075. (Nomodel.)

To all whom, it may concern:

Be it known that I, J osEPH'G. RAoUE'r'r, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Detonators;and I do hereby declare the following to be a full, clear,

- and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

My invention relates to detonating devices adapted to feed and explodedetonators.

The invention is particularly adapted for use in connection with a cane,an umbrella, or like article for use in parades and during campaigns andother celebrations.

The objects of my invention are to provide a safe, effective, and cheapdevice which is adapted to be secured, preferably, to a cane or the likeand when so secured will automatically feed explosives from a magazineto an exploding-chamber and in position so that it maybe exploded,preferably,by forcibly striking the lower end of the device against aresisting substance.

My invention consists in the peculiar construction of the device wherebythe above objects are attained and which will be hereinafter fully setforth and claimed In the drawings, Figure I is a view in elevation,illustrating a device constructed according to my invention, showing thesame with the front plate removed, illustrating the internal mechanismin position when the explosive is about to be operated upon, showing theexplosive in position between the engaging surfaces of the explodingmechanism. This figure also illustrates the position of thefeeding-tumbler in relation to the other parts. Fig. H is a likeillustration to Fig. I, but illustrating the position of the parts afterthe explosion has occurred and showing the feeding-tumbler in positionto receive the explosive from the magazine. Fig. III is a view lookingtoward the magazine end or edge of the device, showing the device withthe front plate attached and in complete condition. Fig. IV is afragmental view of so much .of the de vice as is necessary to illustratethe front of the exploding-chamber and to show the opening for allowingthe gases to escape after the explosion. Fig. V is a detached view ofthe plunger, by means of which the mechanism is put into operation forthe purpose of exploding and feeding the explosive pellets.

In forming my device I preferably cast it of suitable metal and form thebody portion in two parts, which are secured together by means of lugswhich are clamped over the outer edges of the adjacent part. These twoparts when fastened together form a magazine A, provided with afeeding-orifice A, this-magazine being closed at the upper end, as at a,where it maybe provided with interlocking projection and recess a, whichwill cause the parts to register when assembling them. Extending alongthe adjacent edges at one side of the magazine I find it advisable toprovide'a space or opening cf, the object of which is to allow of thefree escape of gases in case of an accidental ignition of the pellets orexplosives when in the magazine, and while this rarely happens provisionshould be made, as hereinbefore stated, to avoid accidents by explosionin case of ignition. In one of the parts of the body portion I provide asocket B, adapted as a ferrule to receive an end of a cane-stick,umbrella, or like article, and thus be securely attached to the same.The socket B is in close juxtaposition to the magazine A, being locatednear the lower end thereof and so positioned that the magazine A. willextend upward at the side of the cane-stick or umbrella with itsfeeding-orifice A facing outward, so as to be easily accessible for thepurpose of feeding the explosives to the magazine. 1

Located beneath the magazine and the socket of the device is theoperating mechanism, which consists of a plunger O and a feedingtumblerD. The feeding-tumbler D is located beneath the magazine A and isprovided with a pocket D, which registers with the bottom of themagazine A and is of such capacity as to receive an explosive pellet,such as P. (See Fig. II.) The tumbler D is so secured in its positionthat it may be oscillated to bring the pocket D first so as to registerwith the bottom of the magazine A and subsequently so as to feed theexplosive to the explosion-chamher, whence by gravity and by beingdirected by the contour of the walls of the explosion-chamber theexplosive pellet will seat itself in position to be exploded. Theoscillation'of the feeding-tumbler is accomplished through the plunger Oin its movement back and forth,and this is accomplished,preferably, byproviding the plunger C with an extension C, which in turn is providedwith a lateral projecting tooth 0, the tooth 0 being adapted to playwithin a recess d, formed in the tumbler D. This recess d is of sucharea as to receive the tooth c and to time its engagement in such amanner that at the full upper stroke of the plunger C the pocket D willregister with the bottom of the magazine and receive the pellet, and atthe lower or outward position of the plunger C the said tumbler willdischarge the pellet and the plunger will be in position to receive thepellet upon an exploding ledge or shoulder 0, thus placing the pelletbetween said shoulder c and an anvil F, against which the pellet ispressed for the purpose of exploding it. The anvil F is preferablyformed integral with the side wall of the explosion-chamber and ispositioned so as to guide the extension C of the plunger C in itsup-and-down movement, acting in conjunction with the .projection f forthis purpose. The plunger C is preferably provided with a lateral lug 0which by engaging the flange 0 the lower end of the explosionchamberretains the plunger in proper relation to the other mechanism when theplunger is in projected position. For the purpose of positiveness ofaction I prefer to employ a spring S, which acts to project the plungerC positively. However, where the plunger is heavy enough and the actionof the device is in a vertical directiori this would not be absolutelyessential. I prefer, however, to employ it, as it enables the plunger toassume its projected position against friction caused by particles ofthe explosives getting between the contiguous surfaces of the movingparts.

The operation of my device is as follows: The magazine A isapproximately filled with a suitable number of explosives in the form,preferably, of pellets P. Then by forcing the plunger C inward thefeeding-tumbler B is oscillated or turned to a position illustrated inFig. II of the drawings, where it receives a pellet P. By raising thedevice through the medium to which it is attached the plunger C ispermitted to be forced outward or downward, causing the tooth c toengage the tum-' bler B and rotate it to the position shown in Fig. I,which allows the pellet P to escape from the pocket D and fall into theposition illustrated in Fig. I, where it is between the upper portion ofthe plunger C, resting on a ledge or shoulder a in position beneath theanvil F. It will now be seen that when the head of the plunger C isforcibly projected or struck against a resisting-surface the pellet iscompressed forcibly between its inner end and the anvil F, and thusexploded, the gases escaping through suitable orifices 0, located at thesides and at the front of the explosionchamber. This justpreviouslymentioned manipulation and effectis repeated, the pellets being receivedby the feeding-tumbler, fed to the explosion-chamber, and exploded insuccession until the magazine is empty.

It will be seen from the above description, taken in connection with thedrawings, that the explosives after having been fed to the magazine arecontained entirely within the device and that the operative part of thedevice, including the exploding mechanism, is shielded from wet and isin a position where it can do no damage, thus avoiding accidents andproviding a reliable detonator.

In setting forth this invention I have shown and described it. inoperation and in assemblage asI consider it best adapted for attainingits objects and have shown and described details of construction as Iconsider them best adapted to perform the functions; but I do not hencewish to be limited to these details, assemblages, or manipulations, asit is evident that they may be departed from and still retain thesalient features of my invention.

What I claim is 1. In a device of the class described, a magazine forexplosives, an exploding-chamber, a feeding device separating themagazine and the exploding chamber, said device being mounted tooscillate onan axis and being provided with a recess and a pocket in itsperipheral surface, a plunger mounted to reciprocate in theexploding-chamber in a line at substantially a right angle to the axisof the feeding device, said plunger extending outside the chamber, atooth projecting from the plunger and engaging with the recess tooscillate the feeding device as the plunger reciprocates, whereby thepocket in the feeding device is caused to alternately receive anddischarge the explosives, and an anvil with which the plunger contactsto explode the explosives.

2. In a device of the class described, a magazine for explosives, anexploding-chamber, an oscillating feeding device having a recess and apocket, an explodingplunger projecting without the lower end of saidchamber, a shoulder intermediate the length of said plunger, an anvilprojecting into the said chamber in position to cooperate with the saidshoulder to explode the explosives, a tooth projeeting from the upperpart of the said plunger, said tooth extending into the recess in thefeeding device whereby as the plunger reciprocates, the feeding devicewill be oscillated to bring the pocket therein alternately intocommunication with the magazine and the explosion-chamber.

3. In a device of the class described, a magazine for explosives, saidmagazine having a slot or space along its side to permit the esber andcooperating with the plunger to .cause the explosive that is in thechamber to be exploded when the plunger is forced inwardly,

and a spring surrounding the protruding por- I 5 tion of the plunger toforce the same outwardly after the explosion.
